Member Function Documentation

get_cliff_edge_distance()

nec_float nec_ground::get_cliff_edge_distance ( ) const

inline

Return cliff edge distance (meters)

Remarks

If there's a cliff problem, returns the distance from the origin of the coordinate system to join between medium 1 and 2. This distance is either the radius of the circle where the two media join or the distance from the X axis to where the two media join in a line parallel to the Y axis. Specification of the circular or linear option is on the RP card.

get_cliff_height()

nec_float nec_ground::get_cliff_height ( ) const

inline

If there's a cliff problem, returns the distance (positive or zero) by which the surface of medium 2 is below medium 1.

get_conductivity2()

nec_float nec_ground::get_conductivity2 ( ) const

inline

If there's a cliff problem, returns the conductivity in Siemens/meter of the ground medium 2.

get_relative_dielectric_constant2()

nec_float nec_ground::get_relative_dielectric_constant2 ( ) const

inline

If there's a cliff problem, returns the relative dielectric constant (no units) of the ground medium 2.
